Abstract: An improved process is provided for treating a porous web (especially fabric) to produce a novel silicone polymer internally coated web.  In the process, a starting curable liquid silicone polymer is coated under pressure upon one surface of the web, and the web is then subjected to localized shear forces sufficient to move the silicone polymer composition into interior portions of the web and to distribute the silicone polymer composition generally uniformly therwithin in such planar region.  Excess silicone polymer composition is wiped away from a web surface.  Thereafter, the resulting web is heated or irradiated to cure the silicone polymer.  Preferably a web is preliminarily impregnated with a fluorochemical.  Webs procuded by this process are breathable, waterproof or highly water repellent, and flexible.

Title: Contour-clamped homogeneous electric field generator

Granted: 1992-03-10
Abstract: CONTOUR-CLAMPED HOMOGENEOUS   ELECTRIC FIELD GENERATOR                 ABSTRACT OF THE DISCLOSURE A contour-clamped homogeneous electric field generator having a plurality of electrodes, each elec-trode being connected to a node which is maintained at a prescribed electrical potential.  The electrical po-tential at the node is maintained by sourcing current into or sinking current away from the node when the voltage at the node varies.  The current source comprises a first transistor having an input terminal connected to a voltage/current supply and an output terminal connected to the node.  The current sink comprises a second transistor having an input terminal coupled to the node, and an output terminal coupled to the voltage/current supply ground.  To control the operation of the first and second transistors, a comparator is coupled to the node for comparing a node-derived voltage to a reference voltage and for providing an oscillating pulse train in response thereto.  The duty cycle of the pulse train varies in response to node voltage variation.  The oscillating output of the comparator is communicated to an RC circuit which averages the voltages of the pulse train, and the averaged voltage is communicated to a control terminal of the second transistor.  When the duty cycle of the pulse train increases, the increased average voltage turns on the second transistor for sinking current away from the node.  When the duty cycle of the pulse train decreases, the first transistor turns on for injecting current into the node.  The first and second transistors thus maintain the voltage at the prescribed level.

Abstract: Méthode pour déterminer la teneur des roches sédimentaires en matière organique à partir de données enregistrées dans un puits par au moins deux sondes de diagraphie mesurant des paramètres différents. Les deux sondes sont choisies l'une pour répondre dans le même sens à une variation de la teneur en eau et en matière organique des roches, l'autre pour répondre de façon très différente à une variation de l'un ou l'autre de ces mêmes constituants et, toutes les deux pour que les lignes I d'iso-teneur en matière organique dans un diagramme à trois pôles, soient sensiblement confondues que le troisième pôle soit le pôle eau PE ou le pôle argile PA. On détermine expérimentalement l'emplacement de la ligne I(0%) et l'on en déduit la teneur en matière organique correspondant à chaque couple de valeurs des paramètres mesurés dans le puits. Dans un diagramme où les paramètres utilisés dépendent, par exemple, du temps de transit T du son dans la roche et de la résistivité électrique Rt des formations, les lignes d'iso-teneur constituent une famille de lignes parallèles. Application à l'étude des bassins sédimentaires.

Abstract: Abstract of the Disclosure An improved control apparatus for an engine having an auto-choking capability is offered by interlock-ing a choke lever and a throttle lever of a carburettor through a temperature-sensitive interlocking rod.  A choke lever of a carburettor is provided with a spring for resiliently biasing a choke in the opening direction.          The choke lever and the throttle lever are connected with each other via a choke interlocking rod made of high molec-ular material such as high molecular urethane elastomer or the like, whose buckling force varies depending upon a temperature.  Upon full opening of the throttle valve at the time of cold state starting of the engine, the choke interlocking rod interlocks so as to close the choke.  Whereas, at the time of hot state starting and warming up of the engine, it interlocks so as to open the choke owing to the resilient biasing action of the spring.  A speed regulating device is connected to the throttle lever.

Title: Virtual instruction cache refill algorithm
Inventor: FITE DAVID B
IPC: G06F9/38
Filed: 1989-08-01
Granted: 1993-11-02
Abstract: VIRTUAL INSTRUCTION CACHE REFILL ALGORITHM            ABSTRACT    An instruction buffer of a high speed digital computer controls the flow of instruction stream to an instruction decoder.  The buffer provides the decoder with nine bytes of sequential instruction stream.  The instruction set used by the computer is of the variable length type, such that the decoder consumes a variable number of the instruction stream bytes, depending upon the type of instruction being decoded.  As each instruction is consumed, a shifter removes the consumed bytes and repositions the remaining bytes into the lowest order positions.  The byte positions left empty by the shifter are filled by instruction stream retrieved from one of a pair of prefetch buffers (IBEX, IBEX2) or from a virtual instruction cache.  These prefetch buffers are arranged to hold the next two subsequent quadwords of instruction stream and provide the desired missing bytes. The IBEX prefetch buffer is filled from the instruction cache after being emptied, but prior to those particular bytes being requested to fill the instruction decoder. This two level prefetching allows the relatively slow process of cache access to be performed during noncritical time.  The instruction decoder is not stalled, waiting for a cache refill, but can ordinarily obtain the desired bytes of instruction stream from the prefetch buffer.

Title: Optical transmitter and/or receiver module

IPC: H04B10/29
Filed: 1989-09-14
Granted: 1992-06-09
Abstract: Abstract Optical Transmitter and/or Receiver Module Such a module is used for communication over optical waveguides. To couple laser light to or from the optical waveguide (3) with as little loss as possible, the laser diode (2) must be precisely aligned with respect to the core region (22) of the end face (14) of the optical waveguide. In conventional modules, this requires costly and complicated mechanical couplers, which nevertheless do not have the necessary long-term stability. To solve the problem of how to provide a low-cost laser-to-fiber coupling which exhibits long-term stability, the optical module (1) is provided with a control facility (16, 17, 18) which controls the coupling of light on the basis of measurements of the differences in reflection factor between the core region (22) and the cladding region (23) of the end face of the optical waveguide (3). For this measurement and control, use can be made of low-priced components employed in CD players.            Fig. 1 G. Veith 2
